(54) | NK-1 receptor antagonists and 5HT3 receptor antagonists for the treatment of emesis |
(57) The present invention relates to a method of treating or preventing emesis in a mammal,
including a human, by administering to the mammal a 5HT3 receptor antagonist and an NK-1 receptor antagonist (e.g., a substance P receptor antagonist). It also relates to pharmaceutical compositions
containing a pharmaceutically acceptable carrier, a 5HT3 receptor antagonist and an NK-1 receptor antagonist. |
